With the intensification of the global energy crisis and environmental crisis, the development and large-scale application demand of high-performance lightweight energy-saving materials and new energy storage materials are becoming increasingly urgent. Magnesium alloys, as the lightest metal structure material, can be energy saving and emission reduction when applied to rail transportation and aerospace. Furthermore, the green and highly secure magnesium-based energy storage materials also show great application prospects. Especially, magnesium and its alloys are the advantageous material resources in China, and thus expanding the wide application of magnesium alloys is of great strategic significance to our country. However, the number of high-performance magnesium alloy grades is obviously small at present. The traditional experimental development severely hinders the promotion and application of magnesium alloys on a larger scale. The key basic data of thermodynamic and kinetics is of extreme importance and necessity for the design and application of high-performance magnesium alloys.Nevertheless,the thermodynamic and kinetics data and data accuracy of magnesium alloys are both quite limited, in comparison with those of steel, aluminum alloys and titanium alloys, etc. It has become a key bottleneck point restricting the optimization of traditional magnesium alloys, the efficient and intelligent development of new high-performance magnesium alloys, and the largescale application of magnesium alloys. Therefore, systematic research on the key basic data of thermodynamic and kinetic of multivariate magnesium alloys, the interaction characteristics and interaction mechanism between alloying elements, and the construction of a systematic high-precision thermodynamic and kinetic databases for multivariate magnesium alloys are one of the key paths to promote the intelligent design of high-performance magnesium alloys and the application of magnesium alloys on a larger scale.
